scsi_hba_tran - SCSI Host Bus Adapter (HBA) driver transport vector
structure
#include <sys/scsi/scsi.h>
Solaris architecture
specific (Solaris DDI).
A scsi_hba_tran_t structure defines
vectors that an HBA
driver exports to SCSA
interfaces so that HBA
specific functions can be executed.

- tran_hba_dip
- dev_info pointer to the HBA
supplying the scsi_hba_tran
structure.
- tran_hba_private
- Private pointer which the HBA
driver can use
to refer to the device’s soft state structure.
- tran_tgt_private
- Private pointer
which the HBA
can use to refer to per-target specific data. This field
may only be used when the SCSI_HBA_TRAN_CLONE
flag is specified in scsi_hba_attach(9F)
.
In this case, the HBA
driver must initialize this field in its tran_tgt_init(9E)
entry point.
- tran_sd
- pointer to scsi_device(9S)
structure if cloning; otherwise
NULL
.
- tran_tgt_init
- is the function entry allowing per-target HBA
initialization,
if necessary.
- tran_tgt_probe
- is the function entry allowing per-target scsi_probe(9F)
customization, if necessary.
- tran_tgt_free
- is the function entry allowing
per-target HBA
deallocation, if necessary.
- tran_start
- is the function entry
that starts a SCSI
command execution on the HBA
hardware.
- tran_reset
- is the function entry that resets a SCSI
bus or target device.
- tran_abort
- is the function entry that aborts one SCSI
command, or all pending SCSI
commands.
- tran_getcap
- is the function entry that retrieves a SCSI
capability.
- tran_setcap
- is the function entry that sets a SCSI
capability.
- tran_init_pkt
- is the function entry that allocates a scsi_pkt structure.
- tran_destroy_pkt
- is the function entry that frees a scsi_pkt structure allocated by tran_init_pkt.
- tran_dmafree
- is the function entry that frees DMA
resources which were
previously allocated by tran_init_pkt.
- tran_sync_pkt
- synchronize data in
pkt after a data transfer has been completed.
- tran_reset_notify
- is the function
entry allowing a target to register a bus reset notification request with
the HBA
driver.
